We report techniques for measuring K/K ratios using a Nu Instruments Sapphire double-focusing MC-ICPMS, equipped with a hexapole collision/reaction gas cell. Large Ar-hydride spectral interferences, as well as the Ar ion beam from the Ar-plasma, are effectively eliminated through a series of ...
conventional MC-ICP-MS mode, through mass filtering and mass shifting using the Collision/Reaction Cell, or in high resolution, using the mass filter in conventional mode. Our users can choose and combine the feature and capabilities they need to best achieve their analytical goals.Read more......
basal cell carcinomacollision tumourdermoscopyBackground: Collision tumours are rare neoplastic lesions consisting of different benign and malignant tumours in the same anatomical site. Various intrinsic and extrinsic factors such as ageing, skin type, UV exposure may lead development of different tumoural...
They pointed out that the effective parameter in the convergence is the cell size to time step ratio, ∆x/∆t (∆x = dx/λ and ∆t = dt/tc, where λ is the gas mean free path and tc is the mean collision time), which should be properly adjusted for any specific test case...
In theory, physical breakage of DNA poses a serious danger to genome integrity and cell survival. Top2 solves this problem by forming a covalent complex between the 51 end of the broken DNA and the tyrosine in the catalytic center (Top2cc). The strong interaction between the two subunits ...
